The old 10-day isolation period for people who test positive for COVID, even if they are asymptomatic, is so 2021.
Going forward, the time to shut it down has been cut in half, as the CDC lowered the isolation period from 10 to 5 days IF they are not showing symptoms. After that, they have to wear a mask around other people for an additional five days the CDC recommended
It took over a year, but the CDC acknowledged that most coronavirus transmissions “occur early in the course of the illness.” Generally, between one and two days after symptoms show up.
Many doctors and disease experts thought the CDC’s old rule of 10 days was far too rigid, even for people who develop symptoms.
Dr. Ashish Jha, the Brown University School of Public Health Dean, sent out a tweet that concurred with the five-day isolation, followed by having two negative COVID test results.
“Having two antigen tests come up negative is a very, very safe way to ensure that you’re pretty much outside of your window of infectiousness.”
Andy Pekosz, a virologist at the Johns Hopkins Bloomberg School of Public Health, told Insider this: “One antigen test is good. A second one adds to that level of security and allows you to feel very confident that someone can go back to the workplace without spreading the virus.”
